Conception and practice of resource utilization, energization and functionalization of coal mining subsidence areas with high groundwater level [PDF]
Underground coal mining often leads to surface subsidence and water accumulation, changes in the ecological environment, as well as in the spatial pattern of land and water resources, in high groundwater level mining areas.

Shuitu Baochi Xuebao, 2022 为探究定位培肥矿区复垦土壤过程中不同有机肥对土壤磷素累积状况及环境流失风险的差异。以山西省孝义市采煤塌陷复垦土壤为研究对象,研究不同有机肥(鸡粪、猪粪、牛粪)和化肥在4个施磷水平下(0,25,50,100 kg/hm2)培肥4年后对矿区复垦土壤全磷、Olsen-P、Mehlich3-P、CaCl2-P以及磷饱和度(DPS)的影响及其之间的变化关系。结果表明:(1)施用有机肥增加土壤中磷素含量,且施磷量越大,对磷素含量的影响越明显,特别是土壤全磷、Olsen-P和Mehlic3-P,并使CaCl2 ...

Shuitu Baochi Xuebao, 2003 采用萌发试验法研究了安太堡露天矿排土场土壤种子库特征,结果表明:排土场土壤中有活性种子存在,且以1年生植物为主,可为植被恢复提供物质基础;随着复垦时间的延长,土壤微环境改善,种子库的组成种类增加,数量增多,幼苗生长加快;复垦10年的沙棘、草地、刺槐林地,土壤种子库组成种类较新排土区明显增多,且优势种因复垦模式不同而异;未复垦的空旷区有利于种子传播,但土壤微环境差,不利于种子萌发,幼苗生长较差.

Shuitu Baochi Xuebao, 2021 为探究改良剂对煤矿复垦土壤有机碳的影响，以山西省襄垣县煤矿复垦区复恳7年的土壤为研究对象，采用田间微区的方法研究了泥炭和腐殖酸对复垦土壤及各粒级水稳性团聚体颗粒态有机碳（POC）和矿物结合态有机碳（MOC）的影响。结果表明：施用泥炭和腐殖酸均能增加复垦土壤水稳性大团聚体（>0.25 mm）含量，但6个月后，水稳性大团聚体会减少，而水稳性微团聚体（2 ...

Shuitu Baochi Xuebao, 2016 以济宁地区引黄充填复垦、引湖充填复垦和预复垦3种复垦方式样地土壤为研究对象，通过分层采样和室内分析，研究不同复垦方式下土壤无机磷（Ca2-P、Ca8-P、Al-P、Fe-P、O-P、Ca10-P）的空间分布情况，并找出影响复垦土壤速效磷偏低的原因。结果表明：（1）3种复垦方式下的复垦土壤全磷含量在0.42～0.77 g/kg之间，土壤速效磷含量在0.65～5.22 mg/kg之间，复垦土壤全磷含量丰富而速效磷偏低；（2）复垦土壤各无机磷形态以难被植物利用的Ca10-P和O-P含量最高 ...

Shuitu Baochi Xuebao, 2020 选择晋陕蒙接壤区永利煤矿排土场沙打旺草地、紫花苜蓿草地、沙棘林地和原地貌草地土壤水分为对象，研究其蒸散、剖面分布、时间变化等特征，以期揭示土体重构及不同复垦植被模式对土壤水分及其时间稳定性影响。结果表明：排土场3种人工植被条件下土壤平均含水量同原地貌草地相比提高了50.7%~62.3%，另外，沙打旺复垦草地土壤含水量显著低于苜蓿复垦草地和沙棘复垦灌木林地（均降低了7.2%）。沙打旺和苜蓿会导致深层（120—260，120—220 cm）土壤水分亏缺，但有利于20—80 cm的土壤水分的保持 ...
